Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
DevBox Tools's answer
DevBox Tools is built on a modern web stack featuring Next.js, TypeScript, JavaScript, and a high-performance backend running on Nginx.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
